"rnEssoRn-GAUGE HOLDER. y

Application filed December V13, 1923i. Serial No. 680,562.

y To all whom t may concern:

Be it known that I, OLor Swanson, a vcitizen `oithe United States, residing at Denver, inthecity andcounty ot. Denver and State ot Colorado, have invented certain new' and .useful Improvements in Pressure- AGauge I-Iolders; and I do declare the tollowing tobe a tuli, clear, and exact description ot the invention, such as will enable others skilled in the art to which it apper-" `tains to make and use the same, reference being had to the accompanying drawings,

and to the characters of reference marked thereon, `which form a partout this specifisure ot the steam. l* i rectness of lthe gauge indicationsshall be (plants it is essential. that the pressure gaugesV employed shall correctly indicate the pres- In order that the corbeyond question, the law as well as common Vprudence requires thatthe gauge shall be removed and tested at stated intervals of about three months. y

It is the object of this invention to produce a (fauve holder that can be Jermanentl connected .toa `locomotive or boiler setting,

and to which the gauge can be applied and` trom which it can be readily removed. It

is a further object ot this invention to produce a holder that can be employed in connection with gauges or" different sizes and which will hold the gauge iirmly and prevent it from loosening when subjected to vibrations. Y

In order better and more clearly to describe my invention, I shall have reference to the accompanying drawing in which the preferred embodiment ot my invention is shown, and in which:

Fig. 1 is a plan view of my improved holder with a gauge secured thereto and .held in place thereby;

Fig. 2 is a side elevation looking in the direction ot arrow 2, Fig. 1;

Fig. 3 is a plan view of the holder with the gauge removed therefrom;

Fig. 4 is a section taken on line 1L-4, Fig. 3; and

` Fig. 5 is a side elevation of the holder, looking in the direction ot arrow 5, Fig. 3.

The same reference characters will be used to `designate the same parts throughout the several views.

My holder comprises a plate 1l shaped some what in thetorm otatruncated isosceles triangle. outwardly inclined lips 2, which are cut from the material of the plate and are adapted to receive the flange. 3 ofthe gauge 1i. -Lugs 5 are cut .from the plate and bent outwardly. These lugs serve as supports for the gauge and spaces the latter from the tace 'of the bracket. Near the vertex of the triangle, I out two 'ribs 6 from the plate and bend the same outwardly so as to form gui-desfor the lug 7. A portion of the plate,

designated by numeraly 8, is lett between the ribs 6 and serves as a guide for the bot- .tom of the lug 7. A memberV 9, Ywhich may be a casting or a forging, is provided at its base with two lugs 10,.by means. of which it is secured tothe plate by rivets 11 or other similar means. `The member 9 is provided with a threaded opening for the reception fot the bolt 12, one end of which is rotatably connected to the lug 7 'and provided with a,A

transverse pin 13. A helicalcompression spring 14 surrounds bolt 12 an-d is located Near each base angle I providek thereon between parts 7 and 9. The upper i end vot bolt 12 hasV a transverse pin 15, which serves as .a` handle 'for rotating the bolt. The lower side ot lug 7 has a notch 16 with which'the'iiange 3 of the gauge 4' engages.

Then the gauge is to beput into place, the i bolt 12 is rotated in such a direction that lug 7 will move upwardly. The gauge is put into place with flange 3 engaging lips 2 and resting on lugs 5 and flanges 6. The bolt 12 is now rotated in the opposite direction, which permits the spring 14 to move lug 7 downwardly against the flange 3 and thereby firmly secure the gauge in place. The spring 14 is always under compression and serves to maintainsuiiicient friction between the bolt and the threaded member 9 to revent the bolt from unscrewing when the older is subjected to constant vibration, as it will be on a locomotive.

Since the range of movement of member 7 may be considerable, it is evident that the holder is adapted to be employed with gauges ot different sizes.

From the above it is apparent that I have produced a holder that is ot simple construction and which can be cheanlv made.

It will accommodate gauges of varying.,r sizes and is provided with friction-producing means that prevent the bolt l2 from turningwhen subjected to vibration.

Having now described my invention, what I claim as new is:

1.- A gauge-holder comprising` a plate adapted to be secured in vertical position on a wall, said plate havinga pair of lugs near its lower end, the inner surtaces of said lugs being spaced from the plate and inclined upwardly and outwardly with respect to 'the plane of the plate so as to engage and hold a flange, a pair of vertically arranged parallel'spaced guidiiig ribs near the upper end of the plate, said ribs extending outwardly trom the plate and having their adjacent sides inclined towards each other, a lug slidably mounted between said ribs so as to b'e guided thereby, means comprising a threaded bolt Yfor moving` said lug upwardly, and means comprising said bolt and a spring` for ymoving,` the lug downwardly.

2. A gauge-holder comprising` a. plate ot substantially triangular shape, apair ot lugs termed integral with the plate and having `their inner Vsurfaces lupwardly and outfjecting .outwardly `from the plane ot the plate rnear the vertex thereof, avlug having` oneendslidably mounted betjveen said ribs, a bolt threadedly connected to the outwardly projecting lug, and having, one end rotatably connected to the slid-able lug, and a spring on said bolt having` `oneend in rictional engagement with the slidable lug.

3. A ygauge-holder comprising a plate of .7 l i l l substantially triangular shape, a pair oit lugs termed integral with the plate and having,v their inner surfaces upwardly and outwardly inclined with respect to the plane thereof, said lugs being located near the base angles ot said plate, a lug projecting outwardly from the plate near the vertex thereof, a bolt threadedly connected to the lug, a gnideway on the plate, said guideway extending in a direction parallel with the bolt, the walls ot said guideway being inclined towards each other so as to form a dovetail slot, a lug slidable in said slot, said s'lidable lug; havingan opening Jor the reception ot the end ot the bolt, and a spring on the bolt,

-said sarine ensralrinr one side ot said lu(r c u D D D and a shoulder on the bolt.

1l. A gauge-holder comprising a plate ot substantiallji,v triangular shape, adapted to be secured in vertical position on a wall, a pair of lugs near the base angles ot said plate, the inner surface ot said lugs being spaced Yfrom the plate and inclined upwardly and outwardly with respect to the tace ol the plate so as to be adapted to engage and hold a tlange on a pressure gauge, guide means located below the vertex of said plate, a lng` having; means cooperating with the guide and adapted to be moved along the latter, a lug projecting outwardly from the sui-tace ot the plate near the vertex ot the plate, a bolt threadedly connected to the outwardly projecting lug; and having one end rotatably connected with a slidable lug,v said bolt having' a portion near its end ot de* creased diameter whereby a shoulder is formed and a helical compression spring between the first mentioned lug' and said shoulder.

lntestimony whereof I alix my signature.
